UN climate report: Humans are ‘dominant’ cause of global warming

The Hill’s Energy & Environment BlogBy Ben Geman

A United Nations climate science panel has concluded there’s at least a 95 percent chance human activities are the main driver of global warming over the last six decades.

“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia,” states Friday’s report from the U.N.’s Intergovernmental Panel on Climate Change (IPCC).

“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes,” the report finds. “It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.”
